Tom Stafford
A Lieutenant General in the U.S. Air Force, Tom Stafford flew on Gemini 6, Gemini 9, Apollo 10, and the Apollo-Soyuz Test Project. On Apollo 10, he and his crew descended to within nine miles of the lunar surface, paving the way for the first moon landing.
On Gemini 9: "[Cernan] lost 10 or 10 1/2 pounds in two hours and five
minutes outside."
So the sun came up, he was still fogged over I said, and also the
communications when he's hooked into the backpack versus the hard line that he
had on there. It was unacceptable. So I called the ground, and ... I called it
quits. I'm going to get him back in before we go into the next nighttime. And
then he slowly worked his way back in. And, of course, I had to pull in the
snake he was on to get him back in. Got him in. See, I didn't do a maneuver
like this and pulled down low a bar we'd designed. And all that meant I went
and used this over the center mechanism I was pressurized like that, then we
wrested it home and then turned the pressure up. And, of course, both our suits
started to inflate. Finally, he just couldn't hardly move. And then when he
opened his visor he was absolutely pink like he'd been in a sauna about an hour
too long. And I had to help him get his gloves off. His hands were pink. So,
what I did was take the water gun and just hose down his face to start cooling
him even though you shouldn't have water splashing around in a spacecraft. I
had to do it to cool him down. And then that night he nearly froze, you know,
with all the water. And I think the data showed the next day we landed and they
flew the suit right back to Houston because we were right off the East Coast.
They had over a pound or a pound and a half of water out of each boot. But he
lost 10 or 10 1/2 pounds in two hours and five minutes outside. So we said wait
a minute, wait a minute. There is a lot we do not know about walking in space
and working and doing tasks in space. So how do we simulate it better? Well,
then the idea came up about using a water tank. And finally, they were able to
do that before Gemini 12. And from that you could ballast a neutral buoyancy
and then hook up the right connections, and you can start to really evaluate
things. So, Aldrin had a very significant increase in capability on Gemini 12.
Now, suppose we'd never done any of this? Say Whoopee! we're going to the moon
and never done it with Apollo it would have been a disaster.
On whether to cut Cernan loose if there were a problem and he were to die:
"Then the pilot chute comes out. Is that going to get snared with what's
left of Cernan?"
Well, what I went on to tell Deke was: Look, I said, assuming I can get through
the retro fire maneuver, then I start the reentry. And the spacecraft doesn't
have too much stability to start with, small margins in stability. We've never
simulated what would happen coming in like this oscillates and here you have
this thing whipping around, it's pretty well insulated and his suit and the
mass of that rocket pack and tether all that whipping around, what would that
do to it? And would it bounce back and forth ... and furthermore, I've got an
open hatch and all I have is this thin suit I was in. Just one layer of nylon
over the bladder, and I've got 3,200-degree plasma coming a couple inches right
about my shoulders through that open hatch. So he's got seven layers of
insulation. That's not going to help him too much he's dead anyway. But I've
got one layer here and this this plasma is going to come through the hatch and
I've got to be rolling the spacecraft back and forth to try to get the lift
back for him to come down here. And suppose we even get through all that and
the parachute comes out—and there's going to be something left there with
that big heavy insulation. Then the pilot chute comes out. Is that going to get
snared with what's left of Cernan? And then here comes the main parachute out.
Is that going to get snared? And then remember Gus' spacecraft sank in Mercury?
And so here I'm going to plop down in the ocean with a hatch open. What happens
then? And he says, Well, what should I tell the NASA management? I said, you
tell them that when the bolts blow I'm the commander and will take care of this
in real time. So anyway, this took a little while to go into all this. So
anyway, I got all suited up, I was lots later than Gene. So we come out and, of
course, we didn't have any sophisticated gear where we could talk back and
forth to each other. And so the first time I could talk we got over to pad 19,
we got in the pad and we plugged in. And he said, hey Tom, what did Deke talk
to you so long about over there? I said he said that he hoped we'd have a good
flight today.
On Apollo 10: "But it was just so unique: you see those big boulders that I
thought were as big as a three- or four-story building. Well, they were bigger
than the Astrodome down in Houston."
Well, it was really unique. First of all, lunar orbit velocity is so much
slower than Earth orbit velocity. You're doing 5,500 feet/second versus 25,700
feet/second. So even though you're lower, you would have more appearance moving
faster, but you're still the relative velocity, you're so much slower. But the
one thing was trying to judge distance down there. Here around the Earth you
get used to an orbit, you look at rivers, you see interstate highways, when the
weather's right, and cities. There's some judging of distance. Up there, there
were no roads, no section lines. There was nothing, no cities to look at in
trying to judge distance. So we had the map that we were going down, we'd put
that out in front of us, put the thumb down and look at these awesome craters
and boulders. Those boulders were what really amazed me.
NOVA: What were you thinking as you were looking at this?
Well, it was just something that I'd never seen before, even though I had looked at the
photos of them. But it was just so unique: You see those big boulders that I
thought were as big as a three- or four-story building. Well, they were bigger
than the Astrodome down in Houston.
